Les, I finally gave up on the migration. I could never get the linux rescue cd to recognize the newly created md partitions with the linux files copied over to them. Interestingly if I changed the Id for the partitions from fd back to 83 and reverted the changes to the /etc/fstab on the md root partition, the linux rescue cd would see both drives as having Linux installations. Also, when still set up for md partitions I always found that when booted from the linux rescue cd that the md partitions would always fail to mount with an 'Input/output error' message. I always had to execute... mdadm --create /dev/md0 --level 1 --raid-devices=2 missing /dev/hde1 ...etc for each md devices. I would then get a warning about this device already existing. I would continue to create it with a 'y' at the prompt after which the md device was available for mounting. However these devices didn't seem to survive a reboot back into the linux rescue cd. I would always get the same 'Input/output error' and have to recreate them with mdadm. I believe I saw the same behavior from the time I initially created them while booted from the hda drive. Weird. Jack ps I tried a variety of things including creating a raidtab and a mdadm.conf in /etc. Neither helped the linux rescue cd recognize the md partitions as a linux installation or allowed the md partitions to be mounted without recreating them in mdadm first.
